Description

It grows as a small to medium-sized tree up to 25 metres in height. It has smooth bark, often in mottled patches of white, light grey, light brown light yellow and pink. Old layers of bark come of in flakes, and it is not uncommon for a few flakes to persist on the trunk for a long time. Young stems may be round or square in cross-section.

Adult leaves are usually a greyish-green or greyish-blue, the same on both sides, lanceolate, 7.5 to 12.5 centimetres long, 1 to 2.8 centimetres wide, on a petiole one to two centimetres long. Flowers are white, and occur in clusters of 9 to 17.

Two subspecies are recognised:
  • E. wandoo subsp. pulverea occurs only in the northern extreme of the species' distribution. Young branches of this subspecies have a waxy coating that is easily rubbed off; and the bark is powdery.
  • E. wandoo subsp. wandoo is the autonym
